The Glendale Police Department is searching for a man who claimed to be a police officer before sexually assaulting two women in separate incidents.

Two similar attacks, one on Sept. 5, the other on Nov. 9, occurred after the women arranged to meet the man at a park near 54th Avenue and Columbine Road, just south of Thunderbird Road, in Glendale, police said.

The meetings were arranged after the man responded to escort service ads posted by the women online, according to police.

Police say the man lured both women to the park to assault them. He reportedly threatened to taser both women and had the sounds of a police scanner coming from his pocket, police said.

Both women told police that the man claimed he was a police officer. He told them if they cooperated with him, they would not be arrested before they were sexually assaulted.
